Friday Squid Blogging: New SQUID
There’s a new SQUID:
A new device that relies on flowing clouds of ultracold atoms promises potential tests of the intersection between the weirdness of the quantum world and the familiarity of the macroscopic world we experience every day. The atomtronic Superconducting QUantum Interference Device (SQUID) is also potentially useful for ultrasensitive rotation measurements and as a component in quantum computers.
“In a conventional SQUID, the quantum interference in electron currents can be used to make one of the most sensitive magnetic field detectors,” said Changhyun Ryu, a physicist with the Material Physics and Applications Quantum group at Los Alamos National Laboratory. “We use neutral atoms rather than charged electrons. Instead of responding to magnetic fields, the atomtronic version of a SQUID is sensitive to mechanical rotation.”
As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

From the Harsh but True files:
If they get ISP’s to help them accomplish this (unlikely, I hope) it is a real security and censorship concern for All – –
To protect all the ‘rill mericuns’ from ‘evil china’, t.RUMP chickenhawk Mike Pompousahole announced:
— the Great American Firewall For Everyone — (or as I typify it: GAFFE) .
How many of these t.RUMP admin. fascists will give up their Chinese made Iphones?
How many are using exclusively non-chinese hardware in their laptops/desktops, etc.?
How much more malignantly isolationist can the t.RUMP administration make the u.s.?
How many recognize this is just more petty retaliation by t.RUMP against tiktok users who devastated the number of people at his rally?
and more importantly,
given the fact that all the ‘wonderful u.s. tech giants’ already hoover up as much of our private info as china might want to, none of this will make this fragmented, disintegrating country more secure!
t.RUMP and his minions are spewing as many phony issues as they can to – –
1) appeal to and incite their knuckle-dragging, drooling base
2) distract from all the destructive effects of his murderous Plague
But, on a more positive note: on techdirt, one commenter recommends people look to security experts and he names Bruce, yea!
Also, I use EFF.org’s privacy badger on firefox. I read about and went to the new EFF site: hXXps://atlasofsurveillance.org/. It uses arcgis (which I have successfully used as embedded in other sites). But after the cute ‘loading’ message I just get a blank white frame. I sent EFF a message on this.
